prospective short-circuit current wave shape to be similar to the 1.2/50 open-circuit voltage wave shape. The
TISP61089S will survive the 2x96 A 1.2/50 as its rating is 2x100 A.
Using a 25
fail at these peak current values as they are higher than the TISP61089S ratings.
These tests use a 2/10 wave shape. As shown in table 3, the peak currents for this test are 2x27 A and 17 A.
The TISP61089S can survive both these levels as its rating is 2x120 A.
Compared to TR-NWT-001089, Issue 1, October 1991, GR-1089-CORE, Issue 1, November 1994, the 2/10
alternative of using a CCITT Recommendation K.22 1.2/50-8/20 combination wave generator has been
changed to an IEEE C62.41 1.2/50-8/20 generator. This generator usually has a single output and a fictive
resistance of 2 . The 2/10 generator has fictive output resistances of 15
compensates for this by adding an extra resistances of 12
generator. In practice, this extra resistance causes the prospective short-circuit current wave shape to be
similar to the 1.2/50 open-circuit voltage wave shape. The TISP61089S will survive the 2x27 A 1.2/50 as its
rating is 2x100 A.
Using a 25
will survive these peak current values as they are lower than the TISP61089S ratings.
